Aleación de magnesio reabsorbible Absorbable magnesium alloy

Descripción Description

La invención se refiere a una aleación de magnesio, según la reivindicación 1 y un implante hecho de la aleación según la reivindicación 4. The invention relates to a magnesium alloy according to claim 1 and an implant made of the alloy according to claim 4.

En la tecnología médica moderna, los implantes se utilizan para una amplia gama de aplicaciones, por ejemplo, para fines ortopédicos, como apoyo a los vasos sanguíneos, y para conectar o fijar los tejidos o los huesos. A menudo los implantes tienen sólo una función temporal hasta la finalización de la curación. Para evitar complicaciones como resultado de estos implantes que quedan permanentemente en el cuerpo, a menudo se deben eliminar o se deben hacer de un material bio anticorrsivo que será gradualmente degradado por el cuerpo. Se conocen un gran número de estos materiales bio anticorrosivos basados en polímeros o aleaciones. De especial interés son las aleaciones hechas de metales biodegradables como magnesio, hierro y tungsteno. In modern medical technology, implants are used for a wide range of applications, for example, for orthopedic purposes, as support for blood vessels, and for connecting or fixing tissues or bones. Often the implants have only a temporary function until the end of healing. To avoid complications as a result of these implants that remain permanently in the body, they must often be removed or made from a bio-corrosive material that will gradually be degraded by the body. A large number of these bio anticorrosive materials based on polymers or alloys are known. Of special interest are the alloys made of biodegradable metals such as magnesium, iron and tungsten.

La Patente Europea 1 270 023 describe una aleación de magnesio que al parecer es adecuada para la fabricación de implantes ortopédicos o endovasculares. La aleación contiene más de un 50% de magnesio y hasta el 5% de metales raros de la tierra. Otros elementos como el aluminio, el litio y el hierro también pueden estar contenidos en la aleación descrita. European Patent 1 270 023 describes a magnesium alloy that is apparently suitable for the manufacture of orthopedic or endovascular implants. The alloy contains more than 50% magnesium and up to 5% of rare earth metals. Other elements such as aluminum, lithium and iron may also be contained in the alloy described.

La aplicación W02008/035948 describe una aleación a base de magnesio biodegradable, compuesta de hasta 40 por ciento de calcio así como más del 40 por ciento atómico de uno o más elementos de indicio. Los elementos de indicio descritos incluyen Zr, Mo, Nb, Ta, Ti, Sr, Cr, Mn, Zn, Si, P, Ni y Fe. Através de la incorporación de los elementos de indicio, el ritmo de degradación de la aleación de magnesio es al parecer muy variada. Application W02008 / 035948 describes a biodegradable magnesium-based alloy, composed of up to 40 percent calcium as well as more than 40 atomic percent of one or more indication elements. The indicative elements described include Zr, Mo, Nb, Ta, Ti, Sr, Cr, Mn, Zn, Si, P, Ni and Fe. Through the incorporation of the indicative elements, the degradation rate of the alloy of Magnesium is apparently very varied.

Se sabe que las aleaciones biodegradables del magnesio también contienen itrio. W002/100452 describe una aleación que comprende opcionalmente 0,01 a 7% en peso de itrio y 0,01 a 8% en peso de metales raros de la tierra. La aleación también puede contener litio y/o aluminio. It is known that biodegradable magnesium alloys also contain yttrium. W002 / 100452 describes an alloy that optionally comprises 0.01 to 7% by weight of yttrium and 0.01 to 8% by weight of rare earth metals. The alloy may also contain lithium and / or aluminum.

El iterbio se ha utilizado como elemento marcador radiopaco en implantes. US2008/0033530 describe una aleación de marcador compuesta por 40 a 90 por ciento atómico de iterbio, así como 10 a 60 por ciento de magnesio atómico y 0 a 10 por ciento atómico de uno o varios elementos seleccionados del grupo Ag, el Zn, Au, Ga, Pd, Pt, Al, Sn, Ca, Nd, Ba, Si, y Ge. Así pues, la aleación tiene una densidad de rayos X suficiente en espesores de materiales bajos. La degradación de iterbio se informa como aproximadamente igual a la degradación del cuerpo principal. Ytterbium has been used as a radiopaque marker element in implants. US2008 / 0033530 describes a marker alloy composed of 40 to 90 percent atomic of iterbium, as well as 10 to 60 percent of atomic magnesium and 0 to 10 atomic percent of one or more elements selected from the group Ag, Zn, Au , Ga, Pd, Pt, Al, Sn, Ca, Nd, Ba, Si, and Ge. Thus, the alloy has a sufficient X-ray density in low material thicknesses. The degradation of ytterbium is reported as approximately equal to the degradation of the main body.

La Solicitud de Patente JP2004099940 describe una ligera aleación de magnesio basada según los informes con una gran resistencia de alta ductilidad. La composición de la aleación comprende de 0,5 a 5 por ciento atómico de elementos de tierras raras seleccionados de Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu y metales diversos metal. La aleación comprende además 0,2 a 4 por ciento de zinc atómico. Patent Application JP2004099940 describes a slight magnesium alloy based on reports with high resistance of high ductility. The alloy composition comprises 0.5 to 5 atomic percent of rare earth elements selected from Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and various metal metals. The alloy further comprises 0.2 to 4 percent atomic zinc.

Una aleación de magnesio resistente al calor con un 6-12% de aluminio se conoce de US 2005/0095166. A heat-resistant magnesium alloy with 6-12% aluminum is known from US 2005/0095166.

La aleación según la invención está relacionada con una aleación bio anticorrosiva y endurecible por envejecimiento, compuesta esencialmente de magnesio, iterbio, zinc y calcio, con componentes opcionales tal como se definen en la reivindicación 1. The alloy according to the invention is related to an anti-corrosive and aging-hardenable bio alloy, essentially composed of magnesium, ytterbium, zinc and calcium, with optional components as defined in claim 1.

El contenido de la invención también incluye un implante que incorpora una aleación de magnesio de acuerdo con cualquiera de las reivindicaciones 1 a 3. The content of the invention also includes an implant incorporating a magnesium alloy according to any one of claims 1 to 3.

Según la invención la aleación de magnesio incluye iterbio, calcio y zinc. Los tres elementos están presentes en las siguientes cantidades: According to the invention the magnesium alloy includes ytterbium, calcium and zinc. The three elements are present in the following quantities:

Iterbio: 0,5 a 8,0 por ciento en peso Zinc: 0,2 a 6,0 por ciento en peso Calcio: 0,1 a 2,0 por ciento en peso Iterbium: 0.5 to 8.0 percent by weight Zinc: 0.2 to 6.0 percent by weight Calcium: 0.1 to 2.0 percent by weight

El balance hasta 100 por ciento en peso incluye magnesio así como inevitables impurezas. Por ejemplo, tales impurezas pueden provenir del proceso de producción de la aleación o de las impurezas contenidas en el material de origen. The balance up to 100 percent by weight includes magnesium as well as inevitable impurities. For example, such impurities may come from the process of producing the alloy or from the impurities contained in the source material.

Sorprendentemente se encontró que las aleaciones de magnesio que contienen iterbio muestran un significativo aumento de la edad de tempabilidad que se utiliza si el zinc y el calcio están presentes. Por otra parte, dichas personificaciones de aleación también presentan propiedades de corrosión favorables que contienen cloro en medios acuosos. Surprisingly it was found that magnesium alloys containing ytterbium show a significant increase in the age of tempability that is used if zinc and calcium are present. Moreover, said alloy personifications also have favorable corrosion properties that contain chlorine in aqueous media.

Esta aleación se produce, en algunas personificaciones, por un proceso de realización de micro-aleación This alloy is produced, in some personifications, by a process of realization of micro-alloy
